Generator::send

Description

Sends the given value to the generator as the result of the current yield
expression and resumes execution of the generator.

If the generator is not at a yield expression when this method is called, it
will first be let to advance to the first yield expression before sending the
value. As such it is not necessary to "prime" PHP generators with a
Generator::next() call (like it is done in Python).

Parameters

value

Value to send into the generator. This value will be the return value of the
yield expression the generator is currently at.
